Abstract

The factors involved in the removal of RNA primers during plastid DNA (ptDNA) replication have been unclear. We now identify a plastid-localized 5′–3′ exonuclease (PEN1) that mediates the removal of RNA primers in ptDNA replication and provide structural insight into its mechanism of action in this process.

质体DNA复制中RNA引物去除的机制

在质体DNA （ptDNA）复制过程中涉及RNA引物去除的因素尚不清楚。我们现在鉴定了一种介导ptDNA复制过程中RNA引物去除的质体定位5 ‘ -3 ’外切酶（PEN1），并对其在该过程中的作用机制提供了结构上的见解。
